Error Capturing in PI 7.1

Hi Experts
I am working on a File to Proxy scenario in PI 7.1 , In one of the field length is 12 char, In some instances Field value will be greater than 12 char, however it passes through the mapping (I have declared as Data type as String with Max length 12) without any error
and It fails in the proxy side, before calling the BAPI
I want to capture the error in PI and send out an email to the user saying that field value is greater than 12
How can I do it in PI
Thanks

YOu can use XML Validation in both adapter engine and integration engine to validate the length > 12 . But downside is enabling xml validation might slow down the performance too.
You can do the following...
In the mapping check the length and if it greater than 12 then decide your receiver is smtp system not proxy.  Based on the length of that field you decide target is either smtp or proxy.

  • Spool Error capture question

    Hi,
    I am trying to spool data from tables into flat files. I am using the following scripts to accomplish it
    1. A cmd file (windows) that makes a call to a sql file
    2. The SQL file which generates another query file at the run time, depending upon the table name passed to it
    3. The run time query file , that executes the final query and spools the data into a txt file | delimited
    For eg:
    Actual command passed C:\Spool_utility\spool_utility TABLE_NAME
    Eg of the spool utility file :
    @echo off
    SET dbuser=XX@YY
    SET dbpw=xxxx
    echo %date% - %time% - Start > %1%log.txt
    echo START
    sqlplus -s %dbuser%/%dbpw% @spool_utility.sql %1>%1.txt
    echo %date% - %time% - Done >> %1%log.txt
    echo DONE
    Eg of the spool_utility.sql
    set echo off
    SET newpage 0
    SET feedback off
    SET linesize 32767
    set pagesize 0
    SET wrap off
    SET recsep off
    SET con off
    SET trim on
    SET trims on
    set verify off
    SET doc off
    SET termout off
    SET arraysize 5000
    SET HEADING off
    set colsep "|"
    spool &1.sql;
    Prompt Select * from &1 where some condition
    spool off
    set termout ON
    @ &1
    EXIT
    The above file generates a table_name.sql file with the actual table name at run time and gets executed and the output is written to the table_name.txt file.
    This works perfectly fine. But the issue is when someone passes some wrong table name or if there is a actual run time error while executing the query , the error with details itself itself gets written to the end spool file.
    For eg : if i do this just to generate an error and execute it from command line, the query generates an error and writes the error to the spool file , but at the command prompt where I executed the command I do not see any error and the process seems to have run perfectly well
    set xxx on xxx off as above
    spool &1.sql;
    Prompt Select * from &1 where rownum><10---this will cause the issue
    spool off
    set termout ON
    @ &1
    EXIT
    Eg of spool file generated :
    from     table_name WHERE rownum><=10 *
    ERROR at line 62:
    ORA-00936: missing expression
    My question is, is there any way i can capture this runtime error and return this error to my calling sql script spool_utility.sql and then propagate it to the calling command file and do some tasks for eg removing the spool file and writing the actual error to a log file . Basically any way to know at my OS calling level that the entire spooling operation was unsuccessful.
    Thanks

    Thanks for the reply.
    Querying the data dictionary will work only when the issue is a invalid table name. My question is can i capture any run time error, not only incorrect table name.
    If there is any run time error (for eg the one I showed where I used a >< sign which is a invalid operator) the error gets written to my spool file, but there is no way I am able to capture that in my calling sql script and subsequently in the calling command file so that I can do something with the error. For eg if a spool file may get written with error messages, some batch process or user may pick up the spool file and start processing which i dont want to happen. i would like to trap that error or at least be notified of the error at my outer calling sql file or outer command file level, so that I can write the error to a log file and delete the erroneous spool file etc.

    Hi,
    In the 5th step (Maintain field mapping and conversion routines) we can write the code, in this step we will get normal abap editor.
    here you can declared the fileds, internal tables and you can call function modules.
    You can capture the records into the internaltable then you can populate the same

  • Error Capturing

    HI,
    1 . We have XI - TIBCO system, and we have a requirement wherein, say, XI sends a Sync inbound message to ECC using ABAP Proxy or IDOC, and say out of the 100 records 25 records failde to update. Is there any way I can capture what these 25 records were and send this info to TIBCO.
    2. We have another requirement wherein we are wanting to capture all the application and system error messages that occur and comeup with a common schema and using this schema send the information to the TIBCO system.
    Any help with this effort, or if any workarounds if we can use would be greately appreciated and ofcourse given points,
    thanks in advance,

    Hi,
    The other way is you can raise an alert from payload , i mean from message monitor.through SAP Alert management you can check , but not system errors.
    see the below link
    You can handle exception in message mapping also...
    /people/alessandro.guarneri/blog/2006/01/26/throwing-smart-exceptions-in-xi-graphical-mapping
    You can use Block step inside BPM error handling....

  • HotSpot Virtual Machine bug?  -- error captured

    My iPM environment crashes without obvious reason or warning. In addition there are numerous and quite frequent errors from threads. Those erorrs do not crash kjs but once those start appearing on kjs I'm forced to restart kjs (at least once a day) because iAS/iPM does not respond to requests.
    Here is an error message that appears on kjs right before kjs crashes:
    # HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
    # Please report this error at
    # http://java.sun.com/cgi-bin/bugreport.cgi

    # Problematic Thread: prio=5 tid=0x3c355cb0 nid=0x29a runnable
    Has anyone seen it and if so is there a "cure"?
    I captured this error by starting iAS from command line. Since there is no way to start 2 kjs' from command line (see more about it in my earlier post) I started one and let "kas -cmd" load the other kjs and iiop (<- also impossible to start from command line)
    Luckily it was the kjs started by me that crashed hence the cmd windows didn't immiediately fold and I was able to get the message.
    Here is hardware/software info:
    iAS6 sp2, WinNT4 Server, 2 processors, 2GB RAM, RAID5. iAS running 2 kjs engines, 1 corba engine

  • General Capture error,capturing straight to MacBook via Firewire 400 to 800

    Hi guys,
    I'm on a shoot now and whilst I'm capturing straight from my Z7 into the Macbook (going from Firewire 400 to 800), occasionally after the capture I get a 'General capture error' and I lose the footage! Obviously it's backed up on tape so it's okay but this is kinda frustrating, do you think it's an issue with the fact that I'm going from 400 to 800?
    I've tried altering the Easy Setup a few times, still having the error.
    Thanks,
    Alex

    In the System Settings/Scratch Disk tab, try activating the "Limit Capture Now To" function. Type in whatever is the longest session you expect to record.
    If you don't activate this feature, FCP has no idea how much material to expect and assumes you will need to fill up your harddrive.
    Let us know if that helps.
    K
    BTW...why don't you tell us exactly what format the Z7 is recording and what your capture settings are. Might also include exact versions of OS/FCP/QT.
    You may just be choking the macbook, by attempting to capture directly to your internal hd.

  • Beta to FCP HD timcode errors & capture presets

    I'm running a BetaSP deck to my G5 and when I attempt to capture I get an error message saying that the timecode was lost and that I have to recapture. The Beta tape I'm using is a professional telecine done from a super-16 print (if that matters). Assuming that there isn't an actual break in timecode from the Beta tape, what else could be causing this? Does it have to do with he capture preset?
    Also, on a side note, when capturing from a BetaSP tape, is there a capture preset that will give me a full quality captured clip?
    This is driving me crazy and if it continues I'm going to have to use Avid and I really don't want to do that.

    I'm running a BetaSP deck to my G5 < </div>
    You're not running it in directly, the Beta has no Firewire output. So how is it connected to your computer and how are you controlling it? Decklink, AJA, Dazzle, DA-Max, Laird?
    The Beta tape I'm using is a professional telecine done from a super-16 print (if that matters). < </div>
    Not in the slightest. Video is video. The film is just video now.
    Assuming that there isn't an actual break in timecode from the Beta tape, what else could be causing this? < </div>
    The communication between your deck and the G5, usually hooked up via your capture hardware, is not working properly. You need to follow the mfr's setup instructions very carefully.
    Does it have to do with he capture preset? Also, on a side note, when capturing from a BetaSP tape, is there a capture preset that will give me a full quality captured clip? < </div>
    Nope, video is video, assuming you get the input configured correctly. But you must use the preset specific to your capture or digitizing device, which you have not told us about yet.
    This is driving me crazy and if it continues I'm going to have to use Avid and I really don't want to do that. <</div>
    What's an Avid? You may have to go back to your Avid if you cannot get your G5 to recognize the hardware between the Beta and Macintosh.

  • FCP5 Error capturing DV

    Hi all
    2 brand new Power mac G5's and FCP 5 arrived at work this morning, woop!
    I've opened one so far.. Fully updated everything.... Tried out FCP and it won't capture!
    This is what I get:
    Logging is fine, and the machine control is too (Sony DSR11) but when it comes to do a batch digitise I get after the first clip "File error: Unknown file". And the same when I try caturing on the fly.
    Thought it may be a prob with the scratch disk being in the boot disk, then added a Lacie Firewire on FW800, still no change (yes I changed the scratch disks to this). Tried both apple firewire and basic firewire but still the same... Oh poo!

    Read this article
    Questions?
    Capturing to your system disk is never advised. Use Firewire not Firewire Basic.
    cheers

    also - Is the search function broken? There are at least 3 other posts on the first page of this forum right now that all ask the same question regarding capturing...

  • WinPE Error Capture and Deploy Win7 - SCCM 2012 R2 w/ CU1

    Hi Forum
    Deploy and Capture: Windows 7 x64
    SCCM Primary single site server: Server 2012 R2
    Version: SCCM 2012 R2 w/ CU1
    Environment is Hyper-V on Windows 8.1, deploying to a Gen1 VM with a legacy adapter.
    I am running into an issue whilst building a lab environment. I have built a Capture and Deploy TS (using the standard TS, ie not MDT although this is integrated) and deployed to an imported machine using the MAC address via PXE. Custom Client package has
    been created and put against the TS.
    The machine picks up the PXE response and boots into the SCCM WinPE environment and I choose the TS. The only currently available TS is the Build and Capture.
    It runs through the TS restarting at various points as expected and then after the Client Manager package is installed it restarts and runs the TS... at this point it starts saying. "Initiating Hardware Devices.." (or something to that effect).
    It does this for about 15 seconds before I get this error:
    Windows PE initialization failed with error code 0x8022001B
    Seen here:
    I am unable to get the cmd prompt up at this point and it will restart and carry on a normal build, no TS running, meaning no capture.
    If any can advise, please do.
    Thanks in advance
    NN

    Hyper-V should work fine without any drivers injected, and you did your VM correctly.
    During this error, what you see in a back ground, ConfMgr wallpaper or Windows 7 black first-run screen "preparing/first run"? I´m just thinking, is there any chance, that you have additional restart step set to boot to WinPE, instead of booting
    to default OS?
    Otherwise, you will need to be able to Access CMD with F8 for more troubleshooting. Make sure you have F8 command Support enabled on boot image and re-distrubute it. Or create new boot image as Peter suggested.  

  • Error capturing SOAP fault for Sync Messages

    Hi
    We have a Sync interface which makes a Proxy call from ECC to PI and then PI makes Soap Sync call to Web application. We are having issues when handling Exceptions. Sender is getting misleading errors in response, even though they are application errors the proxy sender is getting error like MappingObjectNotFound.
    When debug the PI system, PI is truncating error info when it return the reponse.
    Below is the scenario of Synchronous interface:
    ECC(Proxy) -> PI(Soap Receiver Adapter) -> MasterDataApp-(Webserver)
    Below is the actual response from Webserver (Extracted via TCPGW sniffer):
    <?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

      <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">hostname.com</ns1:hostname>
    and then Sync Request mesasge fails with below error because of the unexpected response payload as shown above:

    Hi Laxman,
    SOAP Adapter cannot handle fault responses. I understand your issue. You even want to send the errorneous response from the Webservice as a payload back to the sender. But because of application error from Webservice, you are getting an error in the response message (Mapping Not found). SOAP Adapter cannot handle application error (i.e you will not get the errorneous response in form of payload) . For details please read below:
    The receiver adapter expects a SOAP message as response. For synchrnous calls, a successful response should be returned with HTTP 200. In this case, the content of the SOAP body will be returned to the caller as the response payload. When some error occurs, the SOAP message may contain the SOAP fault element. In this case, when the fault detail element is not empty, its content will be returned as the fault payload in an application error message. For others, a system error message will be returned to the caller.
    HTTP/1.1 200 OK
    Content-Type: text/xml; charset="utf-8"
    <SOAP:Envelope
    xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">

    <Price>34.5</Price>
    </m:GetLastTradePriceResponse>
    </SOAP:Body>
    </SOAP:Envelope>
    will result in an application response message with response payload
    <m:GetLastTradePriceResponse xmlns:m="Some-URI">

    will result in an application error message with fault payload
    <e:myfaultdetails xmlns:e="Some-URI">
    <message>My application didn't work</message>
    <errorcode>1001</errorcode>
    </e:myfaultdetails>
    In order to send the erroneous response as a payload to the sender, you should develop flow in below manner:
    ECC(Proxy) -> PI --> ECC(Proxy)
    In PI make a SOAP lookup. The response of the SOAP lookup will contain the response given by the WebService (it can be a vaid response or an application error in WebService). Now map this response to the proxy...In this way you can handle the application error msgs from webservice..
    I hope this helps you...

  • Dataload process - error capturing process (Best practise to follow)

    I'm pulling data from Oracle db and load into MS-SQL 2008.
    For my data type checks during the data load process, what are options to ensure that the data being processed wouldn't fail. such that I can verify first in-hand with the target type of data and then if its valid format load it into destination table else
    mark it with error flag and push into errors table... All this at the row level.
    One way I can think of is to load into a staging table then get the source & destination table -column data types, compare them and proceed.
    Is this the right approach? Or should I just try loading the data directly and if it fails try trouble shooting(which could be a difficult task as I wouldn't know what caused error...)
    Suggestions please..

    thanks vikas. But he idea of getting the data types n length freaks me out from maintainability point of view.
    can I do things like this dynamical.... Compare destination table-column data type n length vs the data I have received... If u could point me to some ref article ut will be of great help!
    cheers!!!

  • ERROR: capturing outparam - Oracle DB 'Date' via 'introspected procedure'

    Hi,
    We have an introspected stored proc (oracle db stored proc which originally returns Oracle 'Date' ). The introspected 'signature' has output params as 'Feugo.Lang.Time'.
    When we 'call' the procedure from an automatic activity, (just a bare minimum call), we get a compilation error. "Error, contact oracle support - should be Java.Util.Date and not Feugo.Lang.Time" for no fault of ours :(...
    Is there any workaround to the same? The date returned therein is an important and decisive data for us to process contracts. :!
    Thanks in advance,
    Pavan.

    Here is my code
